Check CONFIG_SOCFPGA_SECURE_VAB_AUTH before perform 'is OS booted from FIT' checking in board_prep_linux function. And, fix typo of CONFIG_SOCFPGA_SECURE_VAB_AUTH_ALLOW_NON_FIT_IMAGE.
CONFIG_FIT will be enabled in both ATF and VAB boot flow, thus, board_prep_linux function will always be called by both ATF and VAB boot flow.
board_pre_linux function will do 'is OS booted from FIT' checking, and it will be called before board_fit_image_post_process function.
VAB boot flow expects the OS is always booted from FIT and with VAB signed cerfiticate because the VAB authentication is implemented in board_fit_image_post_process function. So, VAB needs the 'is OS booted from FIT' checking in board_pre_linux function.
However, for ATF boot flow, it is not a requirement that the OS must always booted from FIT. The OS can be booted from individual Image and kernel dtb file. Thus, we should not do 'if OS is booted from FIT' checking in board_prep_linux function.
